M4A ali AAC m'malamulo ambiri, kapena Apple Lossless (ALAC) pamene anachokera ku lossless rip. Vorbis m'ma OGG ndi lossy ndi amagwiritsa ntchito kusinthasintha bitrate mwa kuipa, kotero ubwino ndi kuika monga mbali kuposa fixed kbps figure.

Kodi kusinthira M4A ku OGG ndi gawo lachiwiri la kutsitsa kwa lossy?

Ndikukhulupirira kuti ndinu oyenera, ndipo ndibwino kuti mupange. Mafomu awiriwa ndi owonongeka, choncho OGG encoder akuchita ntchito kuchokera ku audio yomwe yakhala ikuyenda mwa psychoacoustic pass, ndipo masankho ake oyamba amapanga gawo loyamba.

OGG ali woipa hardware thandizo - car stereos, zakale iPods ndi TV ambiri sadzaona fayilo pa zonse.

Kodi ndi bitrate iti yomwe fayilo ya OGG imatha?

Default 192 kbps for lossy OGG; pass-through for lossless OGG. Override to 320 kbps if you want maximum lossy fidelity, 128 kbps for size-restricted podcast distribution, or 96 kbps for voice-only sources where the smaller file matters more than studio detail.
